[email protected] SHORT COMMUNICATION Teucrium L. (Lamiaceae) is a species-rich genus with an almost cosmopolitan distribution and a centre of diversity in the western Mediterranean region (Harley et al. 2004; Salmaki et al. 2016). In Western Australia, fifteen species are currently recognised including six informally-named taxa (Western Australian Herbarium 1998–). A full taxonomic review of the genus in Western Australia is required; however, in accordance with the taxonomic strategy outlined by Wege et al. (2015), we herein formally recognise a new species restricted to areas of high mineral prospectivity, with a view to providing taxonomic certainty for conservation planning and diagnostic information to facilitate future surveys.
